DC station control system, one of the control systems of the converter station, is generally equipped with two sets of redundancy system. CSD(Control Shut Down) function is a control strategy for DC station control system faults. The paper analyzes operation conditions, process, results and so on;according to the actual situa-tion on site, it summarizes factors leading to operation of CSD control function. Furthermore, the paper proposes preventive measures in accordance with field work to prevent maloperation of CSD during normal operation.
